So my Bootloader is currently locked and I can't boot into recovery, it just shows the OnePlus Logo when I try to boot into it.
So currently, I have ParanoidAndroid w/root, can boot into it, can get to FastBoot, can't get into recovery, Bootloader locked, can't unlock it because the Bootloader Unlock option isn't present in this ROM, since it's not the stock ROM,
How It happened
I had the MultiROM Recovery installed, with the Stock ROM installed as the main ROM. I guess through experimenting with it the Bootloader got relocked somehow.
I eventually installed Paranoid Android, and wanted to switch back to regular TWRP, so I flashed it from recovery, that's when I lost access to it, so I booted into PA, used the TWRP app to flash the recovery, still nothing. finally tired to flash with FastBoot, that's when I found out the Bootloader was locked again.
Did "fastboot oem device-info" got this
Code:
(bootloader) Device tampered: false
(bootloader) Device unlocked: false
(bootloader) Charger screen enabled: false
(bootloader) Display panel:
(bootloader) console_enabled: 0
(bootloader) exec_console_unconsole: 0
I tried this Unbrick Guide, didn't work, here's the comment I made over there
Not too sure what to do at this point,
https://forum.xda-developers.com/nexus-5x/help/tp-link-android-phone-adb-device-t3440471 maybe inbox the OP of this thread and see if he found a solution
I figured it out, in the end it's the Mega unbrick guide, but with a step I didn't see mentioned anywhere.
if you can't get your phone to show up as QHUSB_BULK:
Turn off your phone.
Hold Volume Up and plug your phone into you computer,
this will force the phone to show up as QHUSB_BULK.
Then you can use the driver provided in that guide and follow the rest of the steps as stated.
Thanks to this guide I found, https://www.gizmochina.com/2016/07/30/oneplus-series-mega-unbrick-guide-twrp-flashing/

Will this work with the Y71?
Hi there,
I am very new to this topic and have never worked with Adroid before, so please bare with me
Will this process work for the new Vivo Y71? (released in China 1 month ago)
I bought it in Shenzhen a few weeks back and went into a shop in Honk-Kong to have them install Google Play Store. Now, I don't know whether they already rooted the device to install Google Play. How can I see if the device is already rooted?
I have the problem, that some of the system prompts (like, error messages) are still in Chinese. The rest of the OS is in English. I would like to eventually install a ROM with support for German or at least full English support.
I know, lots of questions. Sorry if they're stupid!
best
But there is no custom recovery for Vivo V9 yet. Correct me if I am wrong.

Hello,
So basically I'm stuck in FastBoot.
I wanted to install the Pixel Experience ROM and did a big mistake, I wiped Dalvik, Cache, System and Data, then installed the ROM but no system, I rebooted and since then I am stuck in Bootloader.
My phone didn't turn on at first and I thought I broke it, but then it turned on into FastBoot.
Now it is stuck there.
I tried everything I found on the internet, I even went to the XDA Discord Server for help but nothing worked.
I have the Xiaomi Mi 9, I had the GlobeROM installed.
I don't care about the data, I just want my phone to work again.
I tried:
adb:
- Does not find my device because it is in FastBoot
fastboot:
-fastboot flash recovery (then my twrp, yes I tried three different versions and they worked before on my Mi 9)
-fastboot boot (image) --> FAILED (remote: Failed to load/authenticate boot image: Load Error)
I tried rebooting into recovery, no success.
I tried installing twrp with cmd and powershell both without success.
I tried rebooting with power and vol up, no success.
The twrp installs successfully, but I can't boot into it.
my fasboot oem device-info:
(bootloader) Verity mode: true
(bootloader) Device unlocked: true
(bootloader) Device critical unlocked: true
(bootloader) Charger screen enabled: false
OKAY [ 0.009s]
finished. total time: 0.010s
I tried to flash a stock (for Android Pie) that I downloaded, but my phone turns off during the process and boots again into FastBoot causing the cmd to close everytime.
Please help me, I feel like my phone is broken now.
Feel free to ask any question, I will answer quick as long as I'm not sleeping, because I will refresh this page every 10 seconds I guess.
I have a weird condition. First of all I was using Android 9 with twrp. Everything was fine. Today I decided to install Lineage 17.1 and first of all I needed the A10 stock rom. So I decided to use Official Fastboot rom. Installed and booted. I turn the dev options on.
Used Adb reboot fastboot to get into fastboot mode. Used the commands that I used to use.
fastboot getvar current-slot (it says A)
fastboot set_active b
fastboot erase boot
fastboot flash boot twrp.img (everything was fine. no errors so far.)
fastboot reboot recovery (I press vol+ button)
Phone boots to fastboot mode. when I try fastboot continue it changes slots and boot OS. I tried to flash twrp or orange fox or different versions of recovery to both slot but nothing works. I always end up with fastboot screen.
fastboot oem device-info
(bootloader) Verity mode: true
(bootloader) Device unlocked: true
(bootloader) Device critical unlocked: true
(bootloader) Charger screen enabled: false
OKAY [ 0.016s]
It seems OK?
I cannot install A9 it gives error (rollback protection maybe?)
How can I flash recovery now? Please help.
Edit: I will try to gain root access patching boot.img with magisk. Maybe somehow I gain access to recovery again. -> Got root access but no recovery
Solved. Tried thousands of recoveries and one worked.
Hi,
I tried to root my phone and have taken following steps:
Developer options -> OEM unlock and USB debugging
Boot to fastboot mode -> fastboot flashing unlock
copy the twrp.zip and magisk.zip file to internal storage
after reboot -> fastboot set_active b
and then fastboot flash boot recovery.img (the twrp image)
want to boot to recovery (Power + Volume up) -> don't work
want to boot to system -> don't work (don't know why)
then fastboot flashing lock to make a hard reset and boot with stock image and default settings (I think that was the big mistake)
after that command the phone want to boot and ends with the error system corrupted
Now the phone stucks in fastboot mode and has a locked bootlader.
I can not boot to recovery or to system or flash any images (with fastboot flash system system.img) or unlock the bootloader again (but flashing unlock is not allowed) or change the current slot (The fastboot flashing get_unlock_ability is 0).
This is the fastboot oem device-info:
(bootloader) Verity mode: true
(bootloader) Device unlocked: false
(bootloader) Device critical unlocked: false
(bootloader) Charger screen enabled: false
This is a part of fastboot getvar all:
(bootloader) has-slot:modem:yes
(bootloader) has-slot:system:yes
(bootloader) current-slot:b
(bootloader) has-slot:boot:yes
(bootloader) slot-retry-count:b:5
(bootloader) slot-unbootable:b:yes
(bootloader) slot-successful:b:no
(bootloader) slot-retry-count:a:7
(bootloader) slot-unbootable:a:no
(bootloader) slot-successful:a:no
(bootloader) slot-count:2
(bootloader) secure:yes
(bootloader) serialno:63ba69f84226
(bootloader) product:laurel_sprout
(bootloader) max-download-size:804261888
(bootloader) kernel:uefi
Current slot is b and that slot is unbootable (but as I wrote before I cannot change the slot).
I also tried the mi flash tool, but that also didn't work (or I made a mistake, but I don't think so).
I don't really know what to do next, one option is the edl mode (but i don't know anything about that, if that is the only way, could anyone give my some kind of tutorial) or bring the phone to a technican.
Is there way to change the active slot or the locked bootloader state with the mi flash tool?
Has anyone a tip or an idea what I could try...
to unlock to boot loader without have the flashing ability,
to change the active slot in locked state,
or anything else?
I hope I haven't forgot any important information, if so please write.
I very appreciate any help.
you need first to unlock the bootloader and then change slot. use the latest platform tools avaible
to unlock the bootloader in fastboot you should do:
fastboot flashing unlock
reboot in fastboot mode and then
fastboot flashing unlock_critical
to verify that bootloader is unlocked : fastboot oem device-info
to change slot try
fastboot --set-active=a
or
fastboot set_active a
or
.\fastboot --set-active=a
if you are planning to use miflash tool to flash stock rom, verify that you are in slot "A". DO NOT use "clean all and lock" scrip... just "clean all" script.
if you want to relock the bootloader after flashing stock rom, use the same commands but inversed the sequence.
fastboot flashing lock_critical and reboot to fastboot
fastboot flashing lock and reboot to fastboot
to verify that bootloader is locked again : fastboot oem device-info
@AlexXiaomiMiA3 - take it to the service center or use one of the online services which will re-flash your phone via EDL with an authorized Mi Account. There is no known way around this as of now.
For the future reference and as a warning for others, NEVER lock your bootloader unless you are 110% sure that your phone is 100% stock and 100% working.
